4. Open the recirculating ducts.
5. After the cab has cooled down, regulate
the temperature control to maintain a
comfortable temperature.
6. Reduce the blower speed to be com-
patible with the temperature setting to
maintain a comfortable range.
To heat the cab. Defrost or demist
the windscreen (Fig. 32 and 33)
1. Press the key (3 Fig. 32) to 1 or 2 po-
sition.

Note
If the system is operated at a very
cold temperature setting for an extended
period of time, there is a possibility of
the evaporator starting to ice-up. If this
occurs, or the automatic control shuts
the system down, regulate the tem-
perature knob to a warmer temperature
setting. If icing continues, increase the
blower speed.
Caution
When the tractor is to be out of use
for a long period, or the system is not
being used, it is strongly recommend-
ed that the air conditioning system be
run for approximately 15 minutes every
week. This precautionary measure is to
prevent the compressor leaking gas.
